How to Upgrade the Big Three

Okay thanks for the info.. Well I'm glad to say that I upgraded my Big 3 and replaced my alternator(with stock alt..105 amps) today. I bought regular 2 gauge Duralast Premium battery cable from Autozone for around 30 bucks. This is what I did------ 1. I ran a separate negative battery cable from my batttery to a spot on a metal crossbar.(I drilled a hole) 2. I ran 2 gauge battery cable from the alternator to the positive battery post( I didn't put a fuse in yet , but I plan to add a 150 amp fuse within the next couple of days). 3. I ran a 2 Gauge negative battery cable from my engine manifold(block) to my alternator screw..(Not the positive screw) I fully charged my battery. Started the car and looked at my battery meter on my pioneer deck and it read 14.4 volts at first( I assuming because the battery was fully charged). But I then drove around and played my system loud and my voltage stayed at around 13.8-14.0 volts or so, except for deep bass drops which dropped the voltage to about 13.4-13.5 volts for a fraction of a second or so.. Okay now at night time with my fog and headlights running and the heat on low, my voltage dropped to a steady 13.4-13.5 or so but with deep bass drops it dropped between 12.7-13.0 for a quick second.. So what do you abou this? Can some analyze this and give me some feedback please! Oh and the only thing that I messed up was my belt tesioner.. for some reason it makes a lot of noise now(rattle, sometimes squeal). It's quiet most of the time but sometimes it can get a little loud.. Why is it causing this noise? Thanks for the feedback my fellow bassheads.,.Pioneer DEH-P6800MP

Oh, I didnt know that...Well with the cables they are there now now so I'm not replacing them. I''m pretty sure I got more current flowing now right either way.?? Since I do have extra wires ? Pioneer DEH-P6800MP

What happens when tensioner gives? And I'm still getting more current right then before with the duralast cables right?Pioneer DEH-P6800MP

The belt is nice and tight on there with less then .5 inches of slack. I don't know if it loosens up when I drive it though.. Are the tensioner easy to change.? I'm hoping all I have to do is unloose the 1 bolt, remove the tensioner, replace with new one and tighten bolt back in..Pioneer DEH-P6800MP

ok i was looking at doing the upgrade to my 87 pontiac 6000 =] .... but ive run into sort of a delema i cant find where the alt positive goes im thinking it goes into a relay thats on the drivers side under a cover...so basicaly if thats where it is should i run the thicker gauge into the relay or straight to the battery? ive been really reluctant to run it straight to the battery seeing as it dosent seem to directly go there now....also i was going to be adding a dry or gel battery int he back what would be the appropriate wattage needed in this application for the isolator? and what would be the ideal gauge of wire going from the batterys/alt to the isolator? if someone could help me out this would be very much appreciated thanks

i was looking at the big 3 method and  i saw many versions to it my question is when going straight from the battery  to the alternator (positive) is a fuse required ive seen that written off and on . also the three are negitive batt terminal to chasis. 2nd battery (positive) to alternator and third negitve to engine block ground. on the third one ive seen two verisons to the third they were negitve to engine block ground and alternator to engine block ground. in brief words which is the correct way thanks 1993 sdv
